T o all whom t may concern:

Be it known that l, ARTHUR W. SMITH,

citizen of the United States, and resident of the borough of Manhattan, city of New controlling continuous work sheets and innat terleaved transfer sheets, and for eecting a relative displacement between the' two; and the object of said inventionis to provide simple and efficient means of the character specified. v

To the above and other ends which will hereinafter appear, my invention conslsts of the features of construction, arrangements of parts and combinations of devices set forth in the following description and pointed out in the appended claims. n

In the accompanying drawings, wherein like reference characters indicateI corresponding parts in the different views,

Fig. 11 is a diagrammatic, vertical, fore land aft sectional view showing the disposition ofthe parts as they appear just after severing a previously written blank, or set of blanks, from the continuous work sheet.

I have shown my invention, in the present instance, embodied in a No. 10 Smith Premier machine in which the invention may be' readily included at comparatively little eX- pense and without materially modifying the structural features of the machine as they now exist. It should be understood, however, that the invention may be embodied in other styles of machines, and that certain features thereof may be used without others, or in other combinations. 4In the accompanying drawings only so much of the No. 10 Smith Premier machine is illustrated as may be necessary to arrive at an understanding of my invention in its embodiment therein.

The present construction while capable of a widerange of uses is particularly adapted y for use in connection with continuous work sheets of the fan-fold type in which a plurality of `superposed webs or layers are formed by folding the work sheet longitu dinally so as to present alternately at op osite sides of the folded sheet openings etween the layers in which interleaved transfer sheets are received. l

By my invention l provideI means by which that portion of the continuous work sheet which ,ordinarily curves around .the platen may be brought to ,a straight line position, or. substantially to a straight line position, with another portion of the sheet in the machine ,which is being fed to the platen. This is in order to facilitate a relative displacement, between .the transfer sheets and the work sheet. l have also provided hand actuated means .which at this time may be operated to edect a straight li e backward displacement of the transfer sheet or sheets relatively to the work sheet Means vare likewise provided lfor clamping the work' sheet and holding it during thefrom the work sheet and for automatically positioning a previously written blank in proper position relatively to the clamp and cutter by the actof bringing a new blank to the printing line, all as will` hereinafter more clearly appear.

The frame of the machine comprises corner posts l and a top plate 2.'V Upwardly and rearwardly striking type bars 3 are mounted to limpact against the front face of a cylindrical rotative platen 4; The platen is mounted on a platen shaft 5 provided with finger wheels 6 which are secured to the ends thereof. The platen shaft is normally seated in bearings 7 in .end plates 8 of the carriage. These end plates' are secured by screws 9 to the base 10 of the carriage, which may constitute a paper table,

and is provided with oppositely grooved.

bearings 11 in 'which anti-friction balls or rollers 12 are received. These rollers are likewise received. in oppositely grooved guides 13 in a fixed supporting or guide plate 14. `The carriage is thus supported to travel from side to side of the machine over the top plate, being propelled in its forward or letter space movement in the usual manner through gear wheels 15 which coact with a rack 16 carried by the carriage.

Any suitable main paper feed mechanism may be employed. In the present instance the paper feed mechanism is similar -to that disclosed in the patent to Alexander T. Brown, No. 1,023,808, dated pril 23, 1912. Such mechanism comprises a floating aper guide or apron 17 provided with a guiding member '18 which is substantially U-shaped in cross section and. straddles a supportmg bar or rod 19 carried by the carriage. A bowed leaf spring 20 is receivedl in said guide 18 and bears at its upper free ends against the bottom of the paper apron and at its vcentral bowed portion against the supporting rod 19 to provide spring means for moving the floating paper apron andY the parts carried thereby toward the platen. A set of main paper feed rollers 21 are carried by the ioating paper apron at the introductory side of the platen,and a set of feed rollers 22 are likewise carried by the paper apron near the forward side of the platen and beneath the same. `A platen scale plate 23 is secured to the paper apron and extends adjacentl to the laten beneath the printing line. A release ever 24 is mounted on and fixed to a pivot rod orY rock shaft 25 which receives a pivotal support on the carriage. The upper end of the release lever is provided with a finger iece 26 by which it and the rock shaft may e actuated. The pivot rod er rock shaft 25 carries fingers 27 which mamas vproject forwardly Vfrom the shaft and project over a flange 28 which extends'rear'- wardly from the guide 18. A forward'movey the rock shaft 25 which carries the feedrollerrelease lever 24.

. The right-hand end plate 8 of the carriage. has a lin'e spacing arm or lever 31 mounted thereon, said arm being effective to oscillate a carrier 32. This carrier supports a springpressed, sliding, line spacing pawl .33 which is adapted to co-act with the teeth 34-of a line spacing wheel secured to the right-hand end of the platen. A spring 35 is effective to return the line spacing lever and the pawl carrier tc normal position. kThe line spacing mechanism referred to is similar to that disclosed in the patent to A. T. Brown, No. 887.584, dated May 12, 1908.'

The parts, as thus far described, constitute arpart of the equipment of the No. 10 Smith Premier machine and further detailed description thereof is deemed unnecessary.

T have provided an auxiliary work sheet support which. in the present instance, ex-

tends rearwardly from the carriage and is 'connected to 'travel therewith and support the work sheet `as it is led` to the platen. rThus, supporting arms or side bars 36 are secured by screws 37 to the base of the carriage and extend rearwardly therefrom andv are substantially horizontally disposed where they project rearwardly from the upper end 'of the paper table formed by the base of the carriage. These arms 36 are rigidly united by a sheet metal angle-bracket 38 which-is secured thereto by screws 39.V

The depending iiange 40 of this bracket carries midway in the length thereof an arm 41 secured to the flange by lscrews 42. A shouldered pivot screw 43 is received at its threaded end in a tapped opening in the arm 41 and constitutes a pivot for a roller 44. This roller is provided with a grooved periphery which rolls on a fixed track or supmemes which will hereinafter appear. This cross bar isl adjustably connected to the side arms 36 by any suitable means such as thumb screws 49 which extend through openings in the end portions of the cross bar and are received in tapped openings 50 in the side bars`36. It will be understood that by these means the cross bar 48 rigidly connects the side bars 36 and that the cross bar 48 is adjustable on the side arms or bars 36 to different positions fore and aft of the machine.

A light sheet metal plate or support 51 is secured to the side bars 36 at the under sides of the same by headed screws 5 2. From the foregoing, description it will'be understood that the p lgtel, side arms 36,v

and cross bar v48constitute an auxiliary paper table or support for the work sheet; that said supportextends rearwardly from the carriage and is'sup orted by the rollerl 44 on the track 45 carried by the frame of the machine; and that this auxiliary paper. table or support is'adapted to travel with 'the carriagein the movement of the latter. A slide or carrier, which is designated as a.

Whole by the reference numeral 53, is mounted to ,move fore and aft .of the machine o n thefauxiliary paper table and is auxiliary paper table and is guided in such. movement by the depending flanges 57 of the angle plates 55. The slide is further guided by the ends of the cross plate 54, which are adjacent. to the inner edges of the side bars 36. The construction is such therefore that the slide orv carrier 53 isguided in its fore and aft movements on the auxiliary .paper table or support (36-48-51) but may,l if desired, be .lifted o the latter. Each side of the slide 53 has ixedly secured thereto a trough-like or `substantially U'. shaped member 58 which is open at its upper side and 'forms parallel side walls 59. Centrally disposed in eachtrough-like mem-v ber 58 1s van upwardly projecting pin 60 which is secured at its. lower end to the-associate member 58.] A ywire yguide61 ex tnds across the machine and is provided with depending ends 62.wl:ich are secured to the members 58. The cross barof this guide is thus maintained elevated above the auxiliary paper'table, and the slide which carries it, and is intended to receive the worksheet which is inserted between the guide and the auxiliary paper table or Work sheet support.`

-Thev carrier or slide 53 is intended as a carrler for an interleaved transfer sheet or sheets, and these sheets are connected tothe From an inspection of Fig. 7 it, will be understood thateach transfer or lcarbon sheet 63 isdoubled at its rear end over a thin metal carrier or bar 64. This bar has a sheath 65 pivoted thereto at`66, sothat the sheath and bar act as a jack-knife to bind the folded sheet between them and thus secure one end of the carbon sheet t0 the bar. Both the sheath and bar. are made of sheet metal and occupy but little widthwise space. Each bar 64 is provided'with an aperture 67 by which it may be mounted on one of the pins 60, the body portion of the bar being received in -thel associated trough-like member 58 so that the edges of the bar 'engage the'inner parallel side Walls 59 of said member 58 toprevent a turning or pivotal movement of each bar around its pin 60 when the bars are -in .place on the slide or carrier. From an inspection of Fi 3 it will be understood that any suitab e .number of these bars may be arranged one above another on the pins 60 and that each bar projects from its point of support on the slide or carrier transversely of the machine, and is connected at oneend only. to

the slide.` These bars 64 with the transfer or carbon sheets attached thereto, may therefore be -readily introduced into the folds of the work sheet andY between the layers vthereof and then'oonnected to, the

slide.l In Fig. 9 I have illustrated dia-l grammatically a work sheet, designated as a whole by the reference numeral 68, and

which comprises in the example shown sgperposedl layers or webs 69, 69, 69" 'andl6 'lhe work sheet is folded at its-edges as 1nd1cated'a-t70, the openings between the webs alternating at opposite side. edges of the work sheet." From this view it -will be understood that the bars l64l are introduced betweenthe layers at the openings and that the carbon ortransfer sheets may be introduced with the bars and thus interleaved between the websI or layers of the work sheet, each bar projecting at its free vend into a fold -of-the worksheet.j In the ex-,

ample illustrated in Fig.' 9 provision is made forf .writing an originalg-and .three copies 695,69". and 69, the copiesbe'ing Pro1 dlillced through ythe interleaved transfer 's e ts.

iso

' The slide or-carrier remains indefinitelyinthe osition to'which it. ismoved onthe works eet support, there being sufiiclent friction between the slide and its support to retain it against accidental displacement'- from the position -to lwhich it is-moved, but

4n'ot enou h friction to prevent the slide or carrier om being .moved forward freely with the vcarbon sheetsas lthe latter are fed fao In order brought to a substantially straight line posiforwardly with the work sheet by the usual line spacing mechanism .or paper feed de I vices, as will hereinafter more fully ap ear.

The work sheet as it is fed forward om a suitable source -of supply over the'work sheet support or auxiliary table passes over the rounded side of thebar 48, along' the 4 plate 51, into the bight between the feed rollers and platen, around the platen and un in front ofthe same past the printing line. The paper feed rollers co-act with the work sheet in--the usual manner tofeed it and the interleaved ltransfer sheets forward, the latter carrying forward the slide 53.

that 'the work lsheet 'may be sented in Figs. 5 and 10, where the bottom of the platen is at a -height corresponding substantially to the plane of the auxiliary' work sheet support. The means by which the platen is mounted so that it may be .thus

shifted will'no'w be described.

A platen frame is provided with bearing openings which receive the platen shaft 5. This platen frame comprises end `bars 71. in

which the bearing openings for the platen" shaft are formed and whichare united by a cross-bar 72 and are fixedly connected to the latter'by -pins 73. The cross bar 72 is `carried by arms 74 to' which the cross rod is, ixedly connected by pins 75.. The rear ends of the 'arms 74 are mounted for pivotal movement in the rear of the platen on a supporting rod 76 which vis Ifixed to. the end plates 8 of the carriage. In thismanner the platen frame is mounted to turn'on a pivotal center in the rear of, the platen around the axis ofthe supportifng'rod 76 and to move upwardly -from the dotted line position represented in Fig. 5 to the full line posif tion represented in that figure, It will be understood that in the normal position of theA parts, represented by dotted lines in Fig. 5, theplaten shaft'is supported in the bearings 7 of the carriage, and in a position where .the platen co-acts with the. aper apron and feed rollers 21 and 22 to e ect a forward feed of the work sheet in the usuall manner. Whem however, the platen is shifted from the dotted tothe full line po-` sition, represented in Fig. -5, the platen is separated from the paper feed devices. 17, 21 and 22, and'is moved to aposition where'the bottom of the platen is at aheight which corresponds t0, or substantially to, the plane of the auxiliary work sheet support in the rear of the platen. At this time the' work feed devices' and may-be elevated vto a position, such las that represheet and interleaved carbon sheets at that portionthereof .where it curves around the platen may be straightened out, or do straighten out, to a straight line position coincident, or substantially coincident, with the plane of the work sheet supported on the work sheet support in the rear of the platen, as indicated in Fig. 10. It will be'understood that when the parts are thus disposed the work sheet isA freed from any binding effect of the platen and that the interleaved carbon'sheets may he readily displaced rearwardly relatively to the work sheet and while the latter is held against displacement from the position to which it has been moved.

In-orderf to facilitate a relativel displacement of the carbon sheets I have provided means for engaging and holding the work ,sheet which will now be described.

A frame, designated as a whole by the reference numeral 77, is pivoted at opposlte sides of the carriage to the platen frame, as

indicated at 78. This auxiliary frame comprises side bars 79 which are pivoted directly to the platen frame at 78,' and are united lby a cross bar or rod 80 fixed in bearings in the arm 79 by pins 81. also comprisessheet metal arms 82 fixed to thecross bar 80by screws 83. These arms terminate at 84 andare tapped to receive -the threaded ends of thumhscrews 85 which The frame I are provided with shoulders 86. The Shanks of these thumb screws extend through slots 87 in supporting arms 88 of ya combined clamp and cutter. The shoulders 86 ofthe thumb screws bear against the forward faces of thel arms 88 and bind 'said arms a ainst the arms82 of the-frame so as to maintain the arms 88 and the parts carried thereby -in the position to which they mav be adjusted on the arms 82. The clamp which has been referred to, in the present instance, is in the natu-re of a two-part clamp comprising asheet metal member 89, riveted at 90 to the supporting arms 88 and extending transversely across the machine thro field. The upper end of this member 89 1s bent' rearwardly at 91 and maybe provided with a knife-edge 92 for severing the written blanks from the continuous work sheet.

The other member of the clamp, in the present instance, comprises a member 93 which may be formed of sheet metal and has an engaging edge 94 which coperates with the rear face of the part 91 to clam and .hold the work sheet between said mem ers. The lower or inner. endofv the member 93 is curved around and fixed to a longitudinally extending member 95 of a wire bail or yoke,

as indicated at 96, and as shown in Figs. 1

and. The bent ends 97 of the. connectingbail are arranged outside of the clamping members 89 and 93 and connect with a longitdinally extending member 98 which is hout, or.. substantially throughout, the writin will rbe understoodthat when! the jaws of the clamp are open, as indicated in' Fig. 1, the

'mamas received in a turned or bent portion 99of the member 89. This provides a pivotal" 1 connection between said members andl thus enables" the member 93 'to move from the open position, represented in Fig. 2, to the closed or clamping position, represented in Fig. 5. lBy loosening the thumb screws 85- the clamp as a whole and the cutter 92 may be' adjusted toward and away from the printwork sheet may pass freely between said .jaws and may be clamped thereby when the jaws are closed, as indicated in Fig. 11.

The cross rod 80, hereinbefore referred to, contains a spline groove 100 and constitutes a supporting rod which supports sheet metal bracketlike members or carriers, each designated as a whole by the reference numeral 101. Each of the carriers is mounted on the supporting rod 80'and is adapted to receive anadjustm/ent alongthe same as well :as a .limited pivotal movement thereon. Each member 10,1"carries` an-allXlaly @margin i'eed roller or device 102 which is adapted to -co-act with the work sheet above the print'- ing line, as indicated in Figs. 1 and 2, and to co-aet with the platen t'o effect aforward feed of the work sheet-when the platen is rotated. Each carrierV 101 is dprovided. with a spline 103 which isreceive in the spline groove 100 butwhich, as may -be understood om an inspection of Fig. 6, is smallerl than the width of the groove so as to aii'ord a limited. pivotal movement of each carrier 101 'around'the axis of the supporting rod 80.

Coiled springs 104 surround the supporting I' rod, -one ,of said springs being received hetween the arms of each carrier 101,` and vwith one of its ends en aging the carrier, asv indicated at 105 T e other end l106 of each spring is `received in the spline groove 100, so as t'o anchor that end of each spring to vthe supporting rod80and yet enable the associated xcarrier and the paper feed "device or margin feed roller e adjustedlalol'l the supportin rod. ,From an inspectinnsl5- thepaper eed devices or margin fee Figs. 1 2 an 4 it will be undd'that substantially upright position, indicated in v Figs. 1, 2 and 4, and in order to maintain the auxiliary paper feed devices 102 in icooperative relation with the platen or'the work sheet thereon. Thislocking or hold-` ing means, in the present instance, is con-- structed as follows: A sheet metal bracketk 107 is secured tothe left-hand end plate'of the carriage by a screw 108. This bracket' extends fonwardly and upwardly from the carriage and is formed with an engaging l A edge 109 and with a flange 110 bent 'atright angles to the plane of the body portion of.

the bracket. The relation of the parts is such that when vthe platen is in the -normal position, the bearingportion for the rod 80- on the left-hand side bar 79 co-acts with the .engaging portion 109 of the bracket arm,as

indicated 1n dotted lines in Fig. 5, to prevent Aa pivotal movement of theauxiliary frame 77, and maintainthe auxiliary paper feed rollers 102 .against the platen. The relation i, of the parts is -such -that the left-hand suporting bar 79 of the auxiliary frame stands ehind' the flange 110 and in the upward movement of the platen prevents a forward Swingin movement of `the auxiliary frame around lts' pivots 78 until the upper end ofv `the flange 110 has been cleared. Thus a movement of the auxiliary frame from the normal, or substantially upright position, to the substantially horizontally disposed position, representedin full lines in Fig. 5g, mayl be effected. It will-be understood 'that this` forward pivotal `movement 'ofJ the' auxiliary frame 77 is leffectivey to carry the left-hand bar 7 9 overthe uppe'rend 111 of the flange ,110, the two co-acting at this timeto lock or maintain the platenv in its elevated position, as indicated in full lines in Fig. 5. It'. wvili be seen therefore that as'long vas the platen remains in its normal osition' the auxiliary frame 77 which carries the clamp, knife, and auxiliary feed rollers, will be held against pivotal movement on the platen frame. It will be seen, moreover, that the .frame 177 can only receive a pivotal movementfrom the upright position represented in Fig. 2 to the substantially horizontally disposed position represented 1n full lines in Fig. 5, w en the-platen has been elevated to a position where'the curvedportion of the work; sheet beneath the platen may be brought to a straight line position coincident .whenj e arts are in the-normal cposition 'with thatportienr` of the work sheet which bear .withv a spring --pressure against the' platen, or'theiwork sheet thereon, above the printing line but that such pressure is reeased and-the feed rollers 112' are moved awayfrom the platen when the' frame 77 is moved to the position shown in Fig. 5. g

"I have provided means for locking or holding' the auxiliary frame 77 against ivotalxnovement when it is in the norma or rollers' is supported on the auxiliary work sheet support. Froman inspectionof Figs. 5 and l0 it lwillbe understood that lthe pivotal center 78 on which the auxiliary frame 77 turns,

on the platen frame is located near thev 'rinting line andl slightly below the same. .l t willposed as represented in full lines in Fig. 5, as when the parts are disposed in the normal position represented in Fig. 2 for purposes which will presently appear.

It will be understood, moreover, that the bars 64 are arranged parallel with the axis of the platen and at a uniform distance therefrom. By reason of this fact the'carbon or transfer sheets connected to said bars may be of ,a uniform. length and all terminate at the same point or line, as indicated diagrammatically in Figs. l0 and 11.

In employing my mechanism for use in connection with a continuous fan-fold work sheet the operation is as follows: It should' be understood -fhat `the continuous l'work sheet is ordinarily printed with a series of blanks on each-web; that these blanks are of a uniform size with, we will say, scored inal,`for example, may be a freight bill,` the next afcashiers slip, the third a checkout slip and the fourth a delivery receipt.

The scored or printed dividing lines 'between successive blanks on the first web are represented 'by the reference letter a in Fig.' 1, so that the length ofthe blank on the outermost web in Fig. 1 is between'two successive lines e, .and the companion vforms on the other webs are of a corresponding length. The first writing line on each of these blanks is indicated by the reference numeral 112, and the printing point or line is indicated by the reference numeral '113. Before beginning the work the knife-blade or clamp is adjusted. so that when the first writing line on one blank is at the printing line the top of the next blank toward the end of the sheet will be in register, or substantially in register, with the engaging edge of the knife-blade or clamp, as indicated in Fig..1.

This adjustment having been effected thecontinuous work sheet is taken from its source of supply over the upper curved'face v of the cross bar 48 .and is threaded beneath v the guide bar 61 and carriedy forward over 'the' auxiliary support and over the platen,

fersheets having been connected to the respective bars 64 they are introduced with the'ad of the bars between t-helayers of the work sheet, as represented'in Fig. 9, extending alternately in opposite directions from ing once been determined the cross bar 48 resales their points of support on the carrier or slide to which the bars are detachably connected. j The transfer sheet should be adjusted relatively to the work sheet in the manj ner indicated in Fig. 10 with ythe forward ends of the ,transfer sheets just in the rear of the forward end of the multiple work sheet, so-that .the forward or leading end of the work sheet may be engaged by the clamp, as indicated in Fig. 11, without engaging 75 the transfer sheets.' -When the transfer sheets have been interleaved between the' layers of the work sheet in the manner indicated, and with the bars 64 secured onthe pins 60 of the slide, the leading end of the work sheet may be introduced beneath the platen and broughtbetween themembers of the clamp and engaged thereby at its forward free end while the platen is still maintained the elevated position represented in Fig. 10. The carrier or slide- 53 maythen be moved rearwardly froml the full to` the dotted line position represented in Fig. l0, or until the forward ends of the transfer sheets'are justin the rear of the second set of blanks on the work sheet, or just in the rear of the lined of severance between the first and second set of blanks. -This extent of movement of the carrier or slide 53 havis adjusted on the side bars 36 to a position where it engages. the slide and acts as a 4stop therefor in the subsequent backward movements of the slide. The openings 50 in the sidebars, which provide for adjusting the cross bar 48, are separated a suitable distance apart to enable the bar to be set for blanks of different lengths and to correspond substantially to the adjustmentof the blamp and cutter-blade relatively to the printing` line. When the transfer sheetsl have been displaced rearwardly by the hand actuated slide 53 inthe manner described. the platen will'be lowered to its-operative position indicated in Fi s. 1,'2v and 4. The second blank on the wor sheet will then be in a position to receive the first line of writing, as indicated in Fig. l.' The operator proceeds to. fill in the blank and the matter written will be'copied on the other blanks 115 of the set. When this blankor set ofl blanks have been. filled in the operator turns the platen to-bring the first writing line 112 on the next-blank' to the printing line. This positions the line of severance a between 120 the first and second bills or blanks on the outermost web in register with the cutting blade or knife. The operator may then close the clamp and sever the first set of blanks. which in the beginning of the work are not filled in and may be destroyed. Still maintaining the clamp closed so that it engages the work sheet at the forward end as represented in Fig. 11, but does not engage the forward ends of the interleaved transfer sheets, the operator elevates the platen and turns the clamp to the substantially horizontally disposed position, shown in Fig. 5. The operator then moves the slide or carrier 53 from the forward position, represented in full lines in Fig. 10, to the dotted line position-represented in that figure where it is arrested by thecross bar 48, the operator still .maintaining the clamp closed on the Work sheet. The platen may again be lowered and the work sheet will be in a position to receive the first line of writing on the next outermost bill sheet, as-represented in Fig. l, and to be copied on the companion blanks of the set through the interleaved transfer sheets. After the parts are once set work in this mannercontinues indefinitely,

and no attention is required upon the part ofthe operator to'properly position the work sheet in the machine except that after the colnpletion of each blank the operator brings the first writing line of the next succeeding blank opposite the printing line. Thus after onev bill is written the operator turns the platen to bring the next bill in position to receive the first line of writing. This automatically positions the work sheet so that a previously written blank, or set of blanks, may be properly severed at the dinally with reference to the platen and the' viding linewith the aid of the knife. The work sheet is also properly positioned with reference to the clamp so that the latter slide forward as the carbon sheets areV fed forward with the-bill sheet, and so on the operations are repeated indefinitely'.

From the foregoing description it will be understood that the auxiliary frame which carries the clamp and cutter has the pivotal center on which it is adapted to turn on the platen frame so situated with reference to the printing line that in lowering the platen and carrying the auxiliary frame to an upright position with the work sheet the latter may roll on or around the surface of the platen without being displaced longitudiprinting line. It. will also be understood that this auxiliary frame receives a shifting movement with the platen as the' latter is shifted away from the paper apron but has a pivotal movement independent of its shifting movement in order to carry the margin feed rollers away from the platen, and in order to lock the platen in its elevated position, etc. It will be observed, moreover, that the clamp and knife are mounted for bodily( movement with the work sheet` and with reference to the platen and that the platen is normally maintained by gravity in coperative relation with the feed rollers '21 and 22 What I claim as new and desire to secure.
